Title: Kiyoshi Mizushima: Innovator in Rubber Testing Methods
Introduction
Kiyoshi Mizushima is a notable inventor based in Atsugi, Japan. He has made significant contributions to the field of rubber testing, particularly through his innovative methods for tension stress testing of rubber materials. His work has implications for various industries that rely on rubber products.
Latest Patents
Mizushima holds a patent for a method of tension stress testing of rubber. This method involves continuously elongating a rubber sample at a predetermined speed while measuring the tension stress when the distance between reference positions on the sample reaches a specific elongation. Prior to the actual test, multiple rubber samples with varying hardness are tested under controlled conditions. The data collected is used to determine a statistical function that relates measuring time to the hardness of the rubber. During the actual test, the hardness is measured, and the tension stress is determined based on the established function.
